Hi,
If my cable provider changes my IP while the computer is running, what can I do to update my local hostname? e.g., the part after bvitale..

[bvitale@pcp0010126256pcs ~]$

The reason I ask is because after the IP change, sendmail no longer forwarded my local LogWatch messages properly, because it was trying to send from a hostname that was no longer valid.

Ben

That is the wrong question or strategy. Give your Fedora host a name
other than localhost and there is no more dynamic hostname change

/etc/sysconfig/network --> HOSTNAME=foo.bar.baz

And reflect your hostname in the /etc/hosts file too for IP mapping.

Does my local hostname have to meet some kind of constraint? For example, I chose "vandelay":

[bvitale@vandelay ~]$ cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1       vandelay        localhost

Is my hosts file setup correctly? If yes, then why am I getting errors like this in sendmail:

Aug 3 21:02:07 vandelay sendmail[10299]: My unqualified host name (vandelay) unknown; sleeping for retry

Please help - thanks,

Ben
